Antigua and Barbuda in the context of "Irish indentured servants"

A microstate or ministate is a sovereign state having a very small population or land area, usually both. However, the meanings of "state" and "very small" are not well-defined in international law. Some recent attempts to define microstates have focused on identifying qualitative features that are linked to their size and population, such as partial delegation of their sovereignty to larger states, such as for international defense.

Commonly accepted examples of microstates include five historic European microstates: Andorra, Liechtenstein, Monaco, San Marino, and Vatican City. Malta and Luxembourg are sometimes included in that list but are generally considered too populous to be genuine microstates. Other examples are small, isolated island states in the Pacific Ocean: Nauru, Palau, Niue, Cook Islands and Tuvalu. Some small Caribbean countries such as Saint Kitts and Nevis, Barbados, Antigua and Barbuda, Grenada, Saint Vincent and the Grenadines may be considered microstates by some but are often not included due to them being grouped together as small island countries. Singapore and Bahrain are sometimes considered microstates but some argue are too populous, self reliant or powerful to be considered true microstates and their island status can play an important factor too.The smallest political entity recognized as a sovereign state is Vatican City, with fewer than 1,000 residents and an area of only 49 hectares (120 acres). Some microstates – such as Singapore, Monaco and Vatican City – are city-states consisting of a single municipality.

The House of Windsor is the current royal house of the United Kingdom and other Commonwealth realms. The house's name was inspired by the historic Windsor Castle estate. The house was founded on 17 July 1917, when King George V changed the name of the royal house from the German Saxe-Coburg and Gotha to the English Windsor due to anti-German sentiment during the First World War. There have been five British monarchs of the House of Windsor: George V, Edward VIII, George VI, Elizabeth II, and Charles III. The children and male-line descendants of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, also genealogically belong to the House of Oldenburg since Philip was by birth a member of the Glücksburg branch of that house.

The monarch is head of state of fifteen sovereign states. These are the United Kingdom, Antigua and Barbuda, Australia, The Bahamas, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, and Tuvalu. As well as these separate monarchies, there are also three Crown Dependencies, fourteen British Overseas Territories, two associated states of New Zealand, and one territory.

The Eastern Caribbean Currency Union (ECCU) is one of the world's four regional currency unions. The union is a development of the Organization of Eastern Caribbean States, in which the member countries agree to share the same currency, the Eastern Caribbean dollar (EC dollar).

The ECCU is composed of the nations of Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, St. Lucia, and St. Vincent and the Grenadines and the British territories of Anguilla and Montserrat.

A Commonwealth realm is a sovereign state in the Commonwealth of Nations that has the same constitutional monarch and head of state as the other realms. The current monarch is King Charles III. Except for the United Kingdom, in each of the realms the monarch is represented by a governor-general. The phrase Commonwealth realm is an informal description not used in any law.

As of 2025, there are 15 Commonwealth realms: Antigua and Barbuda, Australia, The Bahamas, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, Tuvalu, and the United Kingdom. While the Commonwealth of Nations has 56 independent member states, only these 15 have Charles III as head of state. He is also Head of the Commonwealth, a non-constitutional role.

Antigua (/ænˈtiːɡə/ ann-TEE-gə; Antiguan Creole: Aanteega), also known as Waladli or Wadadli by the local population, is an island in the Lesser Antilles. It is one of the Leeward Islands in the Caribbean region and the most populous island of the country of Antigua and Barbuda. Antigua and Barbuda became an independent state within the Commonwealth of Nations on 1 November 1981.

The island's perimeter is roughly 87 km (54 mi) and its area 281 km (108 sq mi). Its population was 83,191 (at the 2011 Census). The economy is mainly reliant on tourism, with the agricultural sector serving the domestic market.

Barbuda (/bɑːrˈb(j)uːdə/; Barbudan Creole: Baabyuuda) is an island and dependency located in the eastern Caribbean forming part of the twin-island state of Antigua and Barbuda as an autonomous entity. Barbuda is located approximately 30 miles (48 km) north of Antigua. The only settlements on the island are Codrington and its surrounding localities. Barbuda is a flat island with the western portion being dominated by Codrington Lagoon, and the eastern portion being dominated by the elevated plateau of the Barbuda Highlands, with salty ponds and scrubland spread throughout the island. The climate is classified as tropical marine.

The first inhabitants of Barbuda were canoe-driving hunter-gatherers around 3,000–4,000 years ago. The island was subsequently inhabited by the Arawak and Kalinago. Early settlements by the Spanish were followed by the French and English who formed a colony in 1666. In 1685, Barbuda was leased to brothers John and Christopher Codrington. In 1834, slavery was abolished in Barbuda. Because the entire island had been covered by a single land grant, the Barbudans kept on autonomous cultivation on communal property after slavery's abolition.

This is a list of islands of Antigua and Barbuda. Antigua and Barbuda is an archipelagic state in the Leeward Islands. There are 54 islands in the country, including three main ones.

The Shekerley Mountains are a low mountain range on southwestern Antigua island, in the nation of Antigua and Barbuda and the Leeward Islands of the eastern Caribbean.
